A hand-drawn map showing the possible whereabouts of Melinda Duckett before her son vanished nearly three weeks ago was checked and found not to be credible, sources close to the investigation told Local 6's Mike Deforest.

Since Duckett committed suicide last week, authorities said they have been leaning toward the scenario that she may have staged Trenton Duckett's disappearance.

Shortly after Duckett's suicide, sources told Local 6 News that her divorce attorney shared information about her possible whereabouts the day Trenton vanished.

According to a hand-drawn map published in the Orlando Sentinel, Duckett and her son drove to a gun range in the Ocala National Forest where she was going to fire a rifle she had recently purchased.

Duckett then reportedly got lost driving down Interstate 75 to Florida's Turnpike and some how ended up at the Altamonte Mall, where she told her attorney that she changed Trenton's diaper, the report said.

She then drove to the T.D. Waterhouse Center before getting on the turnpike to head home, the report said.

Police are not publicly commenting on the map, but sources close to the investigation told Local 6 News Friday that they thoroughly checked out the attorney's claims and found them not to be credible.

Witness Comes Forward

A search of the Ocala National Forest will continue Saturday.

Investigators told Local 6 News Friday that a continuing search that began in the Ocala National Forest Thursday was based on an independent witness who claims to have seen and talked with the woman and her son driving around the forest.

"The mother and child were in the car and a partial, at least, conversation took place between the eyewitness and the parties," Leesburg police Capt. Steve Rockefeller said.

During Thursday's search, a child's toy elephant was found, but it apparently does not belong to Trenton.

Gun Investigated

Local 6 News also learned that crime lab technicians are analyzing a .20-gauge shotgun recovered from Duckett's home to see if it is relevant in Trenton's disappearance.

"Melinda did purchase a firearm during the month of August, which is the same month of the reported abduction," Rockefeller said.

The gun Melinda used to kill herself belonged to her grandparents, the report said.

The 21-year-old mother was studying for a career in law enforcement and had experience shooting guns.

"We heard that she did do some shooting, some target practice-type shooting," Rockefeller.

Joshua Duckett, Trenton's father, also confirmed Thursday that when Melinda Duckett was pregnant with Trenton, she was checked into a mental health facility because she was talking about committing suicide

Anyone with information into Trenton's whereabouts is urged to call 800-CALL-FBI.
